摘要
采用嵌埋人工热电偶的方法,通过正交试验研究了干切削SiCp/Al复合材料时切削参数对刀具前、后刀面切削温度的影响。选定切削参数,实验研究了干式切削、压缩空气风冷、油液浇注和MQL等冷却方式对前、后刀面切削温度的影响。试验结果表明,对于车削SiCp/Al复合材料,后刀面温度高于前刀面温度,进给量对刀具温度影响最显著,MQL切削条件下刀具温度最低。
By means of orthogonal experiment method, the effects of cutting parameters on the cutting temperature of rake face and flank of the cutter were investigated with embedded synthetic thermocouples in the dry turning process of SiCp/ZL109 composites. Then with selected cutting parameters, the effects of various cooling manners, such as without any cooling medium, cooling by compressed air, cooling by cutting oil, and cooling by minimum quantity lubrication （MQL） oil spray, on the cutting temperature of rake face and flank of the cutter were investigated by turning experiments. The results indicate that in the turning of SiCp/Al composites, the cutting temperature of rake face is higher than that of flank, and the effect of feed on cutting temperature of the cutter is most notable, and the cutting temperature is the lowest under MQL cooling condition.
